Summary
Banco de Mexico
government central-bank finance enterprise
The Autonomous System of Banco de México, Mexico's central bank and the issuer of the peso. This is the bank's own institutional network, not a service sold to anyone else.
What it's used for
- Corporate and operational connectivity for the central bank: staff offices, regional branches, public-facing sites and the systems behind Mexico's payment and clearing infrastructure.
- Reaching the bank's counterparties in the Mexican financial system over its own routed address space rather than through a commercial ISP's pool.
Notable
- Government / public-institution network, not a carrier. RIS sees 101 IPv4 prefixes carrying roughly 25,856 addresses, but only 2 observed BGP neighbours. That combination is the giveaway: a wholesale carrier of any size peers with hundreds to thousands of ASes because selling reachability is the product. Two neighbours means two upstream transit providers and nobody buying transit from Banxico — the classic multihomed end-site shape.
- Everything sits inside a single contiguous block,
170.70.0.0/16, sliced into a long list of /24s. Deaggregating a held block that finely is normal for an institution that wants per-site traffic engineering across its own upstreams, and it explains why the prefix count is so high against a fairly small address count. It is not a sign of scattered, brokered space.
Interesting
- A central bank running its own AS is a deliberate resilience choice: monetary and payment systems cannot be allowed to inherit a single ISP's outage or its routing policy, so the institution holds the addresses and the AS number itself.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,783 prefixes, as published 2026-10-17. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
